2007-2017 Wrangler JK

While tuning our Go Fast Fox Jeep JK shocks we realized that many people are selecting the wrong length shocks and leaving significant travel unused. It is common to choose Fox JK shocks by looking at lift height. While lift height is a great starting place, it commonly results in people choosing shocks that are too short. In order to maximize wheel travel you want to run the longest Fox JK shock possible without it becoming the bump stop. This means that shock collapsed length is the best way to look at which Fox shocks will fit your JK. Maximum shock collapsed length is determined by the length of the bump stop spacers you’re running.
